The Analysis of Imaging Characteristics of Pulmonary Complications in Leukemia / 实用放射学杂志

ABSTRACT

Objective To improve the diagnostic level of pulmonany complications of leukemia by analysing imaging characteristics.Methods The imaging findings of pulmonary complications were analysed in 200 cases with leukemia.Results The pathogenic agents of pulmonary complications includedinfection of single type of bacteria in 33.5%(67 cases),mixed bacteria infection in 35%(70 cases),fungal infection in 3.5%(7 cases),fungal infection combined with bacteria infection in 5%(10 cases),unknown pathogenic agents in 23%(46 cases).The radiologic findings were as followsthe change of lung markings in 84 cases(42%),lung parenchyma lesion in 116 cases(58%),pleura lesion in 29 cases(14.5%) ,pleural effusion in 19 cases(9.5%), hilum of the lung or mediastina lesion in 40 cases (20%).Conclusion Pulmonary complications of leukemia are mainly pulmonary infection.The diagnosis of this lesion has to combined with clinical data and laboratory test,repeat radiography after treatment is also helpful in differential diagnosis.
